#1599: Make iterative inverses in Arpack always use double-precision
--------------------------+-------------------------------------------------
Reporter: rgommers | Owner: wnbell
Type: defect | Status: new
Priority: normal | Milestone: 0.11.0
Component: scipy.sparse | Version: 0.10.0
Keywords: arpack |
--------------------------+-------------------------------------------------
Comment(by pv):
As far as I understand the situation, commit:8d749358 may already make the
iterative inverses work in double precision (the input vectors are in
double precision). However, the stuff on arpack.py:978 makes it pick the
tolerance according to single precision.
Changes, if any, should be made in IterOpInv.__init__
I think this is again not a release blocker, we can again pick the test
workaround from 0.10.1 if I don't manage to fix this in time...
